Instructions

Naming and Ownership

• This repository/product is Sandbox Agent.
• Gigacode is a separate user-facing UI/client, not the server product name.
• Gigacode integrates with Sandbox Agent via the OpenCode-compatible surface (/opencode/*) when that compatibility layer is enabled.
• Canonical extension namespace/domain string is sandboxagent.dev (no hyphen).
• Canonical custom ACP extension method prefix is _sandboxagent/... (no hyphen).

Docs Terminology

• Never mention "ACP" in user-facing docs (docs/**/*.mdx) except in docs that are specifically about ACP itself (e.g. docs/acp-http-client.mdx).
• Never expose underlying protocol method names (e.g. session/request_permission, session/create, _sandboxagent/session/detach) in non-ACP docs. Describe the behavior in user-facing terms instead.
• Do not describe the underlying protocol implementation in docs. Only document the SDK surface (methods, types, options). ACP protocol details belong exclusively in ACP-specific pages.
• Do not use em dashes (—) in docs. Use commas, periods, or parentheses instead.

Docs Source Of Truth (HTTP/CLI)

• For HTTP/CLI docs/examples, source of truth is:
  • server/packages/sandbox-agent/src/router.rs
  • server/packages/sandbox-agent/src/cli.rs
• Keep docs aligned to implemented endpoints/commands only (for example ACP under /v1/acp, not legacy /v1/sessions APIs).

E2E Agent Testing

• When asked to test agents e2e and you do not have the API tokens/credentials required, always stop and ask the user where to find the tokens before proceeding.

ACP Adapter Audit

• scripts/audit-acp-deps/adapters.json is the single source of truth for ACP adapter npm packages, pinned versions, and the @agentclientprotocol/sdk pin.
• The Rust fallback install path in server/packages/agent-management/src/agents.rs reads adapter entries from adapters.json at compile time via include_str!.
• Run cd scripts/audit-acp-deps && npx tsx audit.ts to compare our pinned versions against the ACP registry and npm latest.
• When bumping an adapter version, update adapters.json only — the Rust code picks it up automatically.
• When adding a new agent, add an entry to adapters.json (the _ fallback arm in install_agent_process_fallback handles it).
• When updating the @agentclientprotocol/sdk pin, update both adapters.json (sdkDeps) and sdks/acp-http-client/package.json.

Change Tracking

• If the user asks to "push" changes, treat that as permission to commit and push all current workspace changes, not a hand-picked subset, unless the user explicitly scopes the push.
• Keep CLI subcommands and HTTP endpoints in sync.
• Update docs/cli.mdx when CLI behavior changes.
• Regenerate docs/openapi.json when HTTP contracts change.
• Keep docs/inspector.mdx and docs/sdks/typescript.mdx aligned with implementation.
• Append blockers/decisions to research/acp/friction.md during ACP work.
• docs/agent-capabilities.mdx lists models/modes/thought levels per agent. Update it when adding a new agent or changing fallback_config_options. If its "Last updated" date is >2 weeks old, re-run cd scripts/agent-configs && npx tsx dump.ts and update the doc to match. Source data: scripts/agent-configs/resources/*.json and hardcoded entries in server/packages/sandbox-agent/src/router/support.rs (fallback_config_options).
• Some agent models are gated by subscription (e.g. Claude opus). The live report only shows models available to the current credentials. The static doc and JSON resource files should list all known models regardless of subscription tier.

Install Version References

• Channel policy:
  • Sandbox Agent install/version references use a pinned minor channel 0.N.x (for curl URLs and sandbox-agent / @sandbox-agent/cli npm/bun installs).
  • Gigacode install/version references use latest (for @sandbox-agent/gigacode install/run commands and gigacode-install.* release promotion).
  • Release promotion policy: latest releases must still update latest; when a release is latest, Sandbox Agent must also be promoted to the matching minor channel 0.N.x.
• Keep every install-version reference below in sync whenever versions/channels change:
  • README.md
  • docs/acp-http-client.mdx
